Efficiently predicting dam-break flow is critical for effective flood risk mitigation. This study introduces a deep learning model, Transformer-ResNet-UNet (T-ResUNet), which integrates Residual Network (ResNet), U-shaped Network (UNet), and Transformer architectures to forecast the spatial and temporal dynamics of dam-break water height and flow velocity. Trained on high-fidelity CFD-DEM coupled simulations, T-ResUNet employs recursive input updates for dynamic predictions. Compared to traditional CFD-DEM simulations, T-ResUNet achieves a 1000-fold increase in computational speed while maintaining near-identical accuracy in long-term water wave morphology predictions. Additionally, it significantly outperforms conventional sequence-driven methods in long-term prediction stability. We results demonstrate the superior capability of image-driven deep learning over sequence-based approaches for capturing physical features in dam-break flow predictions.
